Do Great Astronomy on the Cheap
Why should it cost you thousands of dollars to enjoy astronomy? It doesn’t and it shouldn’t. All you have to do is “look up” on a clear, dark moonless night to enjoy the beauty of the night sky. But what if I want to get a closer look at the moon or Saturn’s rings, for[…]
2024 Hunter’s SuperMoon
The October Full moon is also known as the Hunter’s moon and is the full moon following the Harvest moon.

The Nassau Coliseum is just a few blocks from Hofstra University, where[…]
Peering into the Heart of the Sun with The SDO (with video)
The Solar Dynamics Orbiting Observatory continuously monitors the sun in 10 wavebands, mostly in the extreme ultraviolet part of the spectrum. These UV emissions correspond to super-heated gas in the million-degree range. Our full-featured video is linked below. When observing the sun in visible light, it seems benign enough and is something we’re used to[…]
BREAKING: NEO Asteroid to Strike Earth’s Atmosphere Today!
Jacqueline Fazekas with the Catalina Sky Survey, the Lunar and Planetary Laboratory of Steward Observatory, the University of Arizona, discovered the asteroid just hours ago, about eight hours before its predicted impact.

Going to the Stars, Riding on a Beam of Light!
During his years working in the Swiss Patent Office, Albert Einstein often imagined what it would be like to ride on beam of light. This thought experiment would come to play a key role in the development of his Special Theory of Relativity, one of the four great works produced during his 1905 Annus Mirabilis.[…]
The Enigma of Time
What does it mean, Albert Einstein asked in 1905, to say that a train arrives someplace — in Paris, say — at 7 o’clock? It should be noted that last week, 30 June, 2019, is the 114th anniversary of Einstein’s publication of “On the Electrodynamics of Moving Bodies“, his Special Theory of Relativity. What is[…]

#DarkMatter and #DarkEnergy Explained? Well, not really!
Ever since it was discovered that the rotational dynamics of spiral galaxies were inconsistent with the observed mass of those galaxies, it has been postulated that missing mass or dark matter was responsible. With fellow staff-member Kent Ford, astronomer Vera Rubin announced at a 1975 meeting of the American Astronomical Society the discovery that most stars in spiral galaxies orbit at roughly[…]

Dark Matter – Chasing A Ghost That Doesn’t Exist
This video is the first in a short series on this topic. Many studies of late have been published regarding this enigmatic phenomenon known as “Dark Matter“.

Celestial Navigation in the Age of the GPS
“All I Ask Is A Tall Ship And A Star To Steer Her By” Those poetic words spoken by 19-20th century English poet John Masefield suggest that all that the men who “go down to the sea” need is a star to steer their tall ship by. What’s to be said of this love of[…]
Greek Scholars and the Development of the Constellations
Astronomy is an area where the Greeks displayed a remarkable talent. Observational astronomy, the main focal point where astronomy took an unprecedented leap in Greece, attempted to construct a model of the universe that could account for the observations made by Greek scholars. They explored all imaginable alternatives, and carefully accounted for several different solutions of[…]
The Sounds of Saturn
Saturn is a source of intense radio emissions and, starting in 2002, scientists at NASA have been monitoring that emission using instrumentation onboard the Cassini spacecraft. As a result, NASA was able to convert and translate the radio signals into sound in an effort to better understand the underlying phenomenon. This discovery is just one[…]
Uranus Uniquely placed Tonight, January 23, 2018
Tonight, January 23, 2018, the planet Uranus is uniquely placed in the constellation Pisces within 6 degrees almost due north of the waxing crescent moon. Although the planet’s brightness or magnitude is at the threshold for naked-eye observation, a modest pair of binoculars is necessary to reveal the planet as a greenish-blue “star” and a[…]
The Star That Wouldn’t Die
A long time ago in a galaxy far, far away…. there was this star that, by all known theories of stellar evolution (the study of how stars are born, live and die), should have died. Many stories in the media lately have described this star as the “Zombie” star since, contrary to what should have[…]

Discovered! A Sister World, Earth-Like Planet Orbits Proxima Centauri – Closest Ever!
Its often been said that Three’s a Charm! That is to say, in this case, three stars in the same system with a habitable Earth-like planet in the mix just for good measure! The Alpha Centauri Star System is a Trinary system – three stars linked by gravity, in orbit around a common center. What[…]
Today is Golden Anniversary of First Image of Earth from the Moon
Fifty years ago today, NASA published the first-ever image of the Earth from the moon. Imaged by the intrepid Lunar Orbiter 1, the black and white image above was beamed back from a distance of 380,000 Km (236,000 mi). Lunar Orbiter 1 was the first of five Lunar Orbiters sent to the moon in preparation[…]
Going to the Stars, Riding on a Beam of Light!
During his years working in the Swiss Patent Office, Albert Einstein often imagined what it would be like to ride on beam of light. This thought experiment would come to play a key role in the development of his Special Theory of Relativity, one of the four great works produced during his 1905 Annus Mirabilis.[…]
Where are the five brightest stars in our sky?
Update to this topic: The Ten Brightest Stars (and where they are, with video) – 1. Arcturus Going out to look up at the stars on a clear, dark night can be daunting, if not for its beauty and majesty but for what may seem like an uncountable number of stars; you often hear the[…]
Science Gives Us Hope in a Turbulent World
World renowned physicist, and Advanced Fellow of particle physics in the School of Physics and Astronomy at the University of Manchester, Professor Brian Cox suggests that science not only gives us hope in a turbulent, conflicted and often dysfunctional world but also provides a method of coping with the turbulence. In an August 3rd BBC[…]

At 9:32 AM, EDT on this date forty seven years ago, humanity finally came of age, venturing off our home world, home to all life that we know of since the dawn of recorded history, for a thousand millennia. It has been said, and quite accurately, that for the 21 hours his two companions were[…]
10 Things We Didn’t Know 100 Years Ago
Almost half a million of the people alive today were alive 100 years ago. These same people have seen so much during that time and we’ve learned far more than the great lights of that day could have ever imagined. Ironically, it was through some of those great lights that we have progressed as far[…]
Significant Solar Flare Recorded By NASA’s Solar Dynamics Observatory
A relatively strong, C-class solar flare was observed on Sunday, July 17th by NASA’s Solar Dynamics Observatory. The flare is noteworthy in that the sun has been relatively quiescent, on its way to solar minimum. The image and the accompanying video below are composites, compiled from hard Ultraviolet and X-ray images obtained by the SDO,[…]
Tonight’s Full Moon
Tonight at 22:57 UTC (6:57 EDT), the moon will be 180º from the sun as it is every month at astronomical Full Moon. July’s full moon is otherwise known as the “Full Buck Moon”, the “Thunder Moon” or the “Hay Moon” in North America. At this time of year, buck deer begin to grow antlers,[…]
Tonight’s Southern Celestial Spectacle
As twilight deepens tonight and as you step outside facing south, it’s as though nature was trying to dress to impress, complete with her best jewels! Tonight’s waxing gibbous moon, less than 24 hours before full, is in Sagittarius, set against the far more distant galactic center. Although the sky’s brightness will continue to increase[…]
New Dwarf Planet Discovered
Astronomers using the Canada-France-Hawaii Telescope on Hawaii’s Mauna Kea announced today that a new trans-Neptunian dwarf planet has been discovered.
